Description

Plate type heat exchanger
Technical field
The present invention relates to plate type heat exchanger.
Background technology
In many heat exchanger applications, hope to realize high or very high design pressure, promptly can allow to flow through the high or very high pressure of one or both media in plate space.Also hope to allow this high pressure in the plate type heat exchanger of the above-mentioned type, this plate type heat exchanger has the for example permanent heat exchanger plate that connects through hard solder (brazing).Under the situation that externally reinforced member is not provided, be difficult to realize this high design pressure.
Weakness zone in this plate type heat exchanger is zone, aperture (porthole), promptly directly centers on the zone in aperture.Design pressure in the plate type heat exchanger of these definite current uses in zone.Yet though some design of orifice area will improve design pressure, this design will can not improve another the regional intensity at plate type heat exchanger, and promptly therefore problem will only be transferred.
An example that needs the application of very high design pressure is the plate type heat exchanger that in the cooling circuit that has as the carbon dioxide of cooling agent, is used for evaporimeter and condenser.From the viewpoint of environment, to compare with traditional cooling agent such as freon, carbon dioxide is very favorable in the art.
Summary of the invention
The purpose of this invention is to provide plate type heat exchanger, and more properly allow at least a plate type heat exchanger that flows through the very high pressure of medium wherein with high design pressure.
This purpose realizes that through the initial plate type heat exchanger that limits this plate type heat exchanger is characterised in that the degree of depth is equal to or less than 1.0mm.
The like this little degree of depth of heat exchanger plate is improved the intensity of plate and plate type heat exchanger.The little degree of depth of heat exchanger plate allow on the area such as the little distance between the corrugation element of spine and paddy portion.So little distance means that contact area or the distance between the join domain between the contiguous heat exchanger plate in the plate group also will be shorter between the corrugation element.Therefore, the little degree of depth causes the little distance between join domain, and therefore causes a large amount of this join domain above area.
According to embodiments of the invention, the degree of depth is equal to or less than 0.9mm, more preferably is equal to or less than 0.85mm, and most preferably is equal to or less than 0.80mm.
According to another embodiment of the invention, each heat exchanger plate had the plate thickness t among the scope of being in 0.2≤t≤0.4mm before being shaped.Advantageously, plate thickness t is about 0.3mm.
According to another embodiment of the invention; The hard solder material has the hard solder volume about the heat exchanger zones of plate type heat exchanger; Wherein, First space and second space have the voidage about the area of plate type heat exchanger, and wherein the ratio of the relative voidage of hard solder volume is at least 0.05.The so bigger volume of hard solder material improves the bonding strength between heat exchanger plate, and therefore improves the intensity of plate type heat exchanger.
According to another embodiment of the invention; Each heat exchanger plate limits longitudinal centre line, and wherein, area comprises spine and the paddy portion that is arranged in such a way; Promptly make spine's adjacency of a heat exchanger plate adjoin the paddy portion of a heat exchanger plate, to form a plurality of join domains.Advantageously, at least one extension line that spine and paddy portion edge and center line form inclined angle alpha extends, and wherein, inclined angle alpha is among the 20 °≤α of scope≤70 °.Preferably, inclined angle alpha is about 45 °.This inclined angle alpha provides maximum join domain, and therefore helps the high strength of plate group and plate type heat exchanger.
According to another embodiment of the invention, the extension line of each spine and paddy portion forms positive bevel angle α and forms corresponding reverse caster angle at the opposite side of center line in a side of center line, and wherein, spine and paddy portion form join domain in centerline.This join domain in centerline is provided at the high strength in this zone.
According to another embodiment of the invention, the apart segment distance of spine is arranged and is extended parallel to each other.Advantageously, the distance between the contiguous spine on the area is less than 4mm.Like this little distance between contiguous spine is as explained above to be favourable, and helps a large amount of join domain in area.Advantageously, this distance can be about 3mm.
According to another embodiment of the invention, each orifice area comprises first orifice area, second orifice area, the 3rd orifice area and the 4th orifice area.
